The objective of the study is to investigate head penetration, cup migration, and clinical outcome in total hip replacements using a factorial design. Treatment groups are E-Poly versus ArComXL liners, and 36 mm versus 32 mm head size.
This study is intended to gather short (Pre-operative to 4-years) and mid-term (5-years) information regarding the performance and safety of the commercially available 36mm CERAMAX® Ceramic on Ceramic Total Hip System from a cohort of new study subjects that were not previously involved in the IDE study for this device.
The purpose of this randomised prospective multicenter longterm study is to evaluate the survival rate of the implant, wear and periprosthetic osteolysis of highly cross-linked polyethylene with and without addition of Vitamin E (UHMWPE-XE vs. UHMWPE-X) in Total Hip Arthroplasty.
In total hip arthroplasty several approaches can be used. The newly introduced minimally invasive anterior approach is supposed to cause less damage to tendons and muscles. At the same time there are reports that there are more complications when this approach is used. The direct lateral approach is the most used in Norway and is well documented. There are however those who postulate that there is to high risk of damage to the gluteus medius causing Trendelenburg gait. In the investigators hospital both the anterior and direct lateral approach is used with good result. The investigators main study hypothesis is that there is no difference between the use of anterior or direct lateral approach i total hip arthroplasty in regards to postoperative function and pain, complications, radiological finds (X-ray and MRI), markers for muscle damage (i.e CK-total) or other clinical outcomes.
The purpose of this study is to evaluate the time to total hip replacement in patients with hip osteoarthritis going through both a supervised exercise program and patient education compared to patients going through patient education only. The null hypothesis is: There are no differences in time to total hip replacement between patients with hip osteoarthritis who went through a 12 week supervised exercise program and patient education compared to patients who went through patient education only. Material and methods: 109 patients with both symptomatically and radiographically verified hip osteoarthritis were included in this randomized controlled trial between april 2005 and october 2007. They were randomized to either a 12 week supervised exercise program and patient education (n=55) or patient education only (n=54). Information on if and when total hip replacement is performed will be collected between April 1st and May 1st. Time since inclusion to follow-up will range from 3.5 to 6 years. Data will be collected directly from the study participants by telephone. The main outcome is time to total hip replacement. Status: This study is a prolongation of an on-going RCT (3a-2005-NAR) using clinical outcomes to evaluate the effect of supervised exercise and patient education. The study will be carried out: NAR-Department of Orthopedics, Ullevaal University Hospital.
Using the traditional and hitherto used uncemented hip prostheses achieved good clinical results, but one of the drawbacks is the risk of fracture in the femoral shaft in indbankning of the prosthesis (1-2%). In addition, the bone scan demonstrated that in the years after surgery dropped almost 30% of bone mass in the femoral shaft. This bone loss increases the risk that in the years after surgery, the increased risk of fractures around the prosthesis and in addition to impeding the described bone replacement prosthesis later. The newly developed prosthesis is anchored in the femoral neck and thus not involve the femoral shaft. This ensures a more physiological or normal weight transfer to the femur bone. This contributes to bone mass in long large extent preserved in the years after surgery, so you have a better opportunity later to make a new prosthesis surgery with good results. The new prosthesis should be capable of simultaneously reducing the incidence of thigh pain in the first year after surgery.'
Younger hip patients often need revision of their hip replacement due to wear and loosening. Newer concepts (resurfacing and large head total hip replacement) with articulation surfaces in metal may reduce the wear, increase the longevity of the implant and give an improved function. The possible downside is that these concepts releases metal debris to the body. The investigators wish to see if the newer interventions are a clinical improvement compared to standard. The investigators also wish to investigate the extent of metal released to the body and any effect on the immune system. Finally the investigators wish to investigate the stability of these new implants and their ability to preserve the bone around the implant. The investigators hypothesis is: That the metal on metal articulations will not have better clinical outcomes than standard The resurfacing implant is expected to preserve the bone of the upper femoral bone. The implants are expected to be stabile within the first year.
The purpose of this study is to evaluate the long term effect of exercise therapy and patient education compared to patient education only in individuals with hip OA, and to evaluate predictive factors for changes in hip osteoarthritis both clinically and on x-ray. Main hypothesis H01: There are no significant long term ( 2 years) differences in hip function, quality of life, physical function and radiological changes between those individuals who went through a patient education program and a 12 week exercise therapy program compared to patient education program only. Material and Methods: 109 patients with radiographically verified hip OA are included in the randomized controlled trial; randomized to 12 week exercise therapy program and patient education (n=55) and patient education program only (n=54). Data will be collected 2 years after completed intervention period in the original RCT, and 6 months and 2 years postoperatively for those patients who have undergone total hip arthroplasty. The main outcome is: The Disease Specific WOMAC-Index. Secondary outcome measures are: Hip X-ray, SF-36v2 (quality of life),PASE (activity score), Self-efficacy for pain, isokinetic muscle strength tests, 6 minute walk test, Åstrand's bike test, range of motion. Status: This study is a prolongation of an on-going RCT (3a-2005-NAR). The inclusion, intervention and follow-ups including 1 year follow-up is completed. 2 year post-intervention follow-up will be completed in 2010, 2 year follow-up postoperative for patients undergoing total hip artroplasty will continue throughout 2011. The study will be carried out: NAR-Orthopedic Centre, Ullevaal University Hospital.
A specific group of neurons in the brain produces hypocretin, a peptide which has been established as an important regulator of sleep and wakefulness. Activation of these neurons (increased hypocretin) stabilizes wakefulness; impairing or blocking these neurons (decreased hypocretin) promotes sleep. Evidence suggests that these neurons may be involved in the hypnotic properties of several anesthetics, and play a role in the induction and emergence from anesthesia. In humans there is a considerable inter-individual variability in hypocretin levels. This study aims to investigate how hypocretin levels affect the anesthetic care and recovery of patients undergoing elective hip surgery.
